The old check zipped the padded output with the unpadded source, so pixels never lined up and
it always passed.

The pinning regression only exercised All Edges (and Left Edge in the CPU
unit test), so the reported 'does not work with Top/Bottom Edge' had no
coverage to catch or clear it. This holds the pinned first/last row in a
CPU test at Direction 90, and adds CPU/GPU parity cases for Top (4),
Bottom (6), diagonal directions, and single-edge pinning on shape layers.
CPU pinning verified correct on main: the guards in dst_wave_pin/wave_pin
agree; the gap was that neither edge path was tested.
Shape and text layers have comp-sized effect bounds centred on their
origin, but effects measured positions from the origin: a point at its
default "layer centre" sat at the comp's bottom-right corner, so Twirl
on a centred shape changed nothing and Bulge only its bottom-right
quarter. As in After Effects, effects now work in effect space,
measured from the top-left of the layer's effect bounds.
The renderer moves the layer buffer into effect space for the whole
stack (Buf::rebase, CPU and GPU alike) and hands effects everything
else in it: masks, other layers' pixels for layer parameters (each in
its own effect space, so Set Matte and displacement maps see a whole
shape layer), the layer's own frames (layer_input, also what Puppet,
Roto Brush and the Layer panel read) and the comp camera
(CompScene::rebased). Layer bounds are now right for every effect, so
pin_rect and EffectEnv::bounds_origin go and layer_rect serves edge
pinning too. Adjustment layers still run on the comp below as it is.
effect_bounds / EvalCtx::effect_to_comp replace the repeated "comp size
when there is no source" code; the viewer's effect point handles and
eyedroppers, Puppet pins, the Layer panel (paint, Roto Brush) and the
tracker's Corner Pin output use them.
Project schema 2: opening a schema 1 project moves positions held by
effects on shape and text layers by half the comp size, so set points
keep their place (point parameters with keyframes, Paint paths and
clone positions, Puppet seeds and pins, Liquify and Roto Brush
strokes). Points still at their default become the layer centre;
expression controls, adjustment layers and expressions are left as
they are (docs/architecture.md). The disk cache's render version is
bumped.
Tests: default_effect_points_sit_at_the_centre_of_a_shape_layer and
layer_parameters_see_a_whole_shape_layer (render, both fail before),
effect_points_on_a_shape_layer (GPU vs CPU),
opening_a_schema_1_project_moves_shape_layer_effect_points_into_effect_space
(engine), and the effects migration tests.

Edge pinning (Turbulent Displace's default Pin All, Wave Warp's
Pinning, Bulge's Pin All Edges) holds the layer bounds still: a
comp-sized rectangle for shape and text layers. That rectangle started
at the layer's origin, but a shape layer's content surrounds its origin
(anchor 0,0), so everything left of or above the origin counted as
outside the layer and was pinned: only the bottom-right quadrant of a
centred shape moved.
The renderer now passes the bounds' top-left in layer coordinates
(EffectEnv::bounds_origin): (-w/2, -h/2) for layers without a source
rectangle, (0, 0) otherwise. util::pin_rect places the bounds there and
the three effects use it on the CPU and the GPU. Effect point
parameters keep their current layer coordinates.
Test: edge_pinning_displaces_all_of_a_centred_shape_layer,
edge_pinning_on_a_shape_layer (GPU vs CPU).

- Transform: Use Composition's Shutter Angle / Shutter Angle, sampling the transform across
the shutter via EffectHost::params_at (EffectEnv::shutter carries the comp shutter when
motion blur is on); the GPU path defers to the CPU when blurring.
- Glow: Glow Operation (blend modes) and Glow Colors > Arbitrary Map.
- Cartoon: Advanced > Edge Enhancement (shock-filter sharpening / softening).
